Thank you for the response Luke. I read the doc and did a little more investigation on my use case, and I see that the problem is more complicated than I'd thought. For example, my plan to naively skip duplicated META-INF/LICENSE files would have violated the license terms of those libraries... For some file types it may be appropriate to rename duplicates (eg, LICENSE-apache-activemq-5.8.0.jar, LICENSE-google-guava-1.0.14.jar) but perhaps that sort of thing is a better job for a function in a build script rather than something baked into the tool itself.
In any case, the real issue for me was apparently that jarsigner won't sign jars with duplicate entries, and it was better not to use a single monolithic jar anyway. I'm still happy to help if I can, but I think I will take a look at the list of issues for community newbs :) Thanks, Kyle On Fri, May 10, 2013 at 2:04 AM, Luke Daley <luke.da...@gradleware.com>wrote: > > On 10/05/2013, at 8:26 AM, Kyle Mahan <kyle.ma...@gmail.com> wrote: > > > I'm interested in helping out on this issue if possible: > http://issues.gradle.org/browse/GRADLE-2171 ("Add an option to avoid > duplicate entries when creating a zip file").
